KEYLESS LOCK.

Application filed April 24, 1922. Serial No. 556,272.

To all whom it may concern:

Be it known that l, WALTER Brazen, a citizen of Poland, residing at Hamilton, Province of Ontario, and Dominion of Canada, have invented certain new and useful Improvements in Keyless Locks, of which the following is a specification.

This invention relates to new and useful improvements in looks, and more particularly to a keyless combination lock, and it is the principal object of the invention to provide a lock of this character which is conveniently attached to a door or the like and which is of simple and inexpensive construction.

Other objects of my invention consist in the novel feature of construction, combination and arrangement of parts as will be hereinafter referred to and more particularly pointed out in the specification and claims.

In the accompanying drawing, forming a material part of-this disclosure Figure 1 is a front view of a lock constructed according to the present invention.

Figure 2 is a cross section through the same on line 22 of Figure 1.

Figure 3 is a longitudinal section on line 33 of Figure 1.

Figures 4 and 4 show in detail front and edge views, partly in section one of the combination discs.

Figures 5 and 5 show in side and end views a boltguide.

Figures 6 and 6 show front and side elevations respectively of a tumbler disc.

Figures 7 and 7 are front and end views of a washer.

Figures 8, 8 and 8* show side, top plan and end views respectively of a locking bolt.

Figure 9 illustrates the working of the combination.

Figure 10 is a front view of a modified form of lock constructed according to the present invention, particularly intended for use with sliding doors.

Figure 11 is a top plan view of the same, partly in section on'line 1111 of Figure 10.

Figures 12 and 12 are side and top plan views respectively of a bolt used with the lock illustrated in Figures 10 and 11.

The lock illustrated in Figures 1 to 9 comprises a casing 10, adapted to be secured to a door 11 by means of fastening bolts 12, entering suitable eyes 13 on the casing 1O.

The front plate 14 is hingedly secured as at 15 to the casing 10 allowing access to a chamber 16 formed by a partition 17.

The locking bolt 18 has a head 19 at one end and a plurality of rack teeth 20 at the upper edge on its opposite end, and is guided in a guide 21 provided with a longitudinal groove 23. v

On this guide a plurality of discs is rotatably arranged, the front disc 24 of which, as shown in detail'view in Figure 4 is larger than the others and provided with a round central opening 25 and square edged channel openings 26 in communication with said opening 25. This disc turns in a depressed aperture 22 of the door. A pin 27 is secured to disc 24, and the outer edge of the disc carries the combination numerals generally indicated at 28.

'The following discs are constructed as for instance disc 29 illustrated'in Figure 6 with a round central opening 30' and a square channel 31 communicating with-this opening. The outer periphery of this disc is provided with shoulders 32 and 33 for engagement by pin 27. Y

A washer 34 of a construction illustrated in Figure 7 is interposed betweene'ach two of the tumbler discs, andeach washer is provided with .acentral opening 35 and square channel. openings 36, and carries a key 37 in its opening 35 adapted to engage the groover 23 of the guide. The bolt 18 is operated by means of a knob 38 and its movement is limited by a collar 39. The

If it is assumed the lock is locked, it can be opened by lifting the plate 14 and turning the disc 24 until a certain number on its periphery comes in line with a mark 41 onwall 17. The numbers of the combination are so selected that any further rotation of disc 24 will bring its pin 27 into successive engagement with the shoulders 32 of the various rings indicated by various combination numbers so that their square channel parts will successively be brought into alignment and allow an operation of the bolt by means of the knob 38, the shaft 42 of which carries a ratchet 43 in engagement with the teeth 20 of the bolt rack to the casing 44 allowing access to a chamcombination numbers,

part.

The'lock illustrated in Figures 10 to 12 is particularly intended for use with sliding doorsor the like, and comprises acasing 44, adapted to be secured to one part 45 of a sliding door by means of fastening bolts 46 passed through suitable eyes 47 or the casing 44.

The front plate 48 is hingedly secured ber 49 formed by a partition 50.

The locking bolt 51 has a head 52 at one end anda longitudinally extending opening 53 at its opposite end, the upper edge wallof which is formed with rack teeth 54.

This bolt is guided in a guide 55 and extends out of the casing, and is adapted to enter a chamber-56 formed in the other part5? of the sliding door. Thebolt 51 is operated by a knob 58 carrying. a,toothed wheel 59 engaging the rack teeth 54.

A plurality of discs is rotatably arranged upon guide 55, and these discs are constructed in 'the'same manner'as described above with respect to the form of my invention illustrated in Figures 1 to 9.

The front disc 60 is larger than the other discs 61 and carries at its outer edge the generally indicated at 62'.

The device operates asiollows:

. Assuming the door is locked, it can be opened by' turning the discs according to the combination for bringing their channels into alignment-so that the head 52 of the bolt can pass throu h them whent-he knob 58 is operated to raw the bolt from casing 10 so that now the sliding door can be opened;

Having'thus described my invention what ,I claim is,--

1. A look of the character described comprising agrooved bolt guide,a large periorated combination disc and a plurality oi smaller perforated, shouldered tumbler discs on said guide, washersbetween each two, oi said discs keyed to. said guide, a bolt movable in lsaid guide, a head on said bolt movouter periphery, a pin on. said disc, a plurality. of smaller tumbler discs o n'said'guide, shoulders on said smaller discs adapted to be operated by said pin to rotate said discs to bring their perforations into alignment, allowing an operation of said bolt, means for operating said bolt, and combination numbers on the outer periphery of said larger disc for successively indicating the engagement of said pin and shoulders for bringing the perforations in said discs in alignment for allowing a passage of the bolt head.

3; A look of the character described, comprising a rooved bolt guide, a large perforated combination disc on said guide pro vided with a central opening, and a square channel part in communication with said opening, a lateral pin'on said large disc, a plurality of smaller perforated discs, shoulders on said smaller discs adapted to be en-' g'aged by said pin to align the perforations of all of said discs, washers between each pair of said discskeyed to said guide, a locking bolt having a shaft adapted to be passed a through the perforations of said discs, ahead on said bolt, rack teeth at one end of said bolt, a pinion in engagement with said teeth, a knob for operating said pinion and bolt to lock and unlock the lock when the perforations of said combination and tumbler discs are in alignment. I

4. A look of thecharacter described comprising a casing adapted to be attached to one part'of a sliding door, a headed bolt, a

bolt guide in said casing, aplurality of tumbler discs in said guide -fprovided with channels, a large channeled disc on said guide laterally, disposed to said tumbler disc carrying a pl'urality of combination characters on its periphery, the channels of the discs adapted to be successively brought into alignment upon theproper setting of the combination to allow the passage of the bolt head, a shank on said bolt adapted to enter a chamber in the second part of a sliding door, an opening in said shank, 'a plurality of rack teeth formed in the upperedge or the wall forming said shank opening, an

operating bolt, and a gear on said bolt in P mesh with said rack teeth for operating said bolt to draw its'he'ad through the aligned channels of the tumbler discs for allowing an opening of the sliding door. H
